Tiedou Used Excavator Recommendation (Issue 15) Caterpillar CAT4-7 ton conventional small hydraulic excavator

　　In the first and second quarters of 2024. small excavators accounted for 67% of the excavator sales market, and Tiedou used excavators accounted for 72% of the sales of excavators within 10 tons. Because of market saturation and the wide application range of small excavators, they are more popular with users at low prices. Under the competition of many brands and prices, many manufacturers' small excavators have simplified configurations, and even many excavators have increased failure rates due to defects in accessories. However, some companies have been strictly controlling the standards of quality and performance. Among them is Caterpillar.

　　The pursuit of low prices in the short term seems to be able to gain some market share, but with the compression of prices and the reduction of costs, the qualified rate of some parts will also decrease. I may not have problems in three to five years, and the reputation will also decrease as the working time increases and the failure rate increases. Product quality cannot ignore the product itself because of cost reduction. Caterpillar is a leader in the field of construction machinery. Whether it is performance or product accessories or purchased parts, they are very demanding and serious. The new and old models are not inferior in product reliability. Many domestic and foreign customers have always trusted Caterpillar based on product quality. Tiedou has used the market feedback of the excavator market for Caterpillar. The appreciation and recognition of Caterpillar is very high. Some old users have purchased CAT excavators from Tiedou for two or three years and the equipment has been running stably. This is also the core of a product.

　　Currently, Tiedou's inspection of used excavators is not only tested by equipment, but manual work is an important link. A series of tests, such as the stability of the equipment under simulated working conditions, the engine power and speed temperature of the small excavator, the maximum flow of the hydraulic pump, the smooth operation and sensitive operation of the excavator equipment, etc., can ensure the performance and quality of a used excavator. Caterpillar has never let us down. Although the price of CAT excavators circulating in the market is slightly higher than the average price of other brands of excavators in the market by 3-7%, the excavator test pass rate is over 98%. Minor defects can also be easily solved. Caterpillar Tiedou is highly recommended for users who need a small excavator.
